New research from Rice University suggests sulfur keeps Mercury’s interior molten at lower temperatures, offering new clues to how the planet’s strange...
Using the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have characterized the atmosphere of TOI-5205b,...
Using the Immersion Grating Infrared Spectrometer (IGRINS) on the Gemini South telescope at the International Gemini Observatory, astronomers have directly...
A new analysis of isotopic signatures across planets and meteorite parent bodies suggests our home world formed entirely from inner solar system material,...
Kepler-51 is a young G-dwarf star hosting three super-puffs and one low-mass non-transiting exoplanet. Kepler-51d, the coolest transiting planet in this...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have for the first time identified hydrogen sulfide gas in the atmospheres of three gas-giant...
The Moon formed from a giant impact of the proto-Earth with the ancient protoplanet Theia. In a new study, a team of scientists from the United States,...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected doubly deuterated water (D2O), or ‘heavy water,’ in the protoplanetary...
The discovery of 1I/Oumuamua, 2I/Borisov and 3I/ATLAS showed that significant numbers of interstellar objects populate interstellar space. Their omnipresence...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected silicate clouds in the atmosphere of the exoplanet YSES-1c and a circumplanetary...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected water, carbon monoxide, and silicon monoxide in the dayside atmosphere of WASP-121b...
Described in a paper that appears today in the journal Nature Astronomy, the discovery means habitable exoplanets could have started forming much earlier...
WASP-132 is a unique multi-planet system in that both an inner rocky planet and the newly-discovered outer giant planet are in a system with a hot-Jupiter...
In 2003, Hubble provided evidence of a massive exoplanet around a very old star. Such stars possess only small amounts of heavier elements that are the...
The newly-discovered exoplanet orbits TOI-3261 (also known as TIC 358070912), an inactive main-sequence star located 300 parsecs (978.5 light-years) away...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have captured high-resolution images of eight protoplanetary disks in Sigma...
The Moon may have been captured during a close encounter between a young Earth and a terrestrial binary (a system of the Moon and another rocky object),...
